Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Choose the polysaccharide that functions as energy storage.
A
Pectin
B
Chitin
C
Starch
D
Peptidoglycan
Explanation: 

Detailed explanation-1: -Glycogen: This polysaccharide is the polysaccharide found in animals to store energy and is composed of alpha-1, 4-glycosidic bonds with branched alpha-1, 6 bonds present at about every tenth monomer.

Detailed explanation-2: -One of the best known polysaccharides is starch, the main form of energy storage in plants. Glycogen is an even more highly branched polysaccharide of glucose monomers that serves the function of storing energy in animals.

Detailed explanation-3: -Answer and Explanation: The polysaccharide that is stored as an energy source in the body of animals is glycogen. Glycogen is a polysaccharide made of branched chains of glucose. Glycogen stores energy in the liver and the muscle of animals.

Detailed explanation-4: -Polysaccharides are very large polymers composed of tens to thousands of monosaccharides joined together by glycosidic linkages. The three most abundant polysaccharides are starch, glycogen, and cellulose.

Detailed explanation-5: -Starch is a storage form of energy in plants. It contains two polymers composed of glucose units: amylose (linear) and amylopectin (branched). Glycogen is a storage form of energy in animals. It is a branched polymer composed of glucose units.
